Aside from the stud pattern (5x114.3), the offset and width of the rim is also very important to know. I had a look at the auction and it states a +40 offset and 8-inch rim width, which should be fine.
Just so you know, the higher the offset is (+) the closer the wheels will sit to the suspension components, and the lower the offset is (-) the further the wheels will sit away from the suspension components and the closer it will sit to the fenders. If the offset is too high (+40 or more) then the wheels will hit/rub against the struts/springs, but if the offset is too low (-35 or less) then the wheels will scrape on the fenders. Either way, both problems are fixable by either using spacers or rolling the fenders, but a +40 offset should be just what you need.
Changing the size of your wheels/tyres also has an affect on your speedometer. I'd highly suggest using the calculators on this site to work out how much of a difference there will be. Just input the size of your old wheels and tyres as well as the size of your new wheels and tyres and it'll tell you exactly how much your speedometer will be affected by:
